When it comes to troubleshooting issues with your lawn mower, one common component that may need testing is the ignition coil. The ignition coil is responsible for generating the electrical spark that ignites the air-fuel mixture in the engine’s combustion chamber. If the ignition coil is faulty, your lawn mower may not start or run smoothly. In this article, we will discuss how to effectively test the ignition coil on your lawn mower.
Step 1: Remove the Spark Plug
To begin the testing process, you will first need to locate the spark plug on your lawn mower and carefully remove it from the engine. Make sure the spark plug wire is still connected to the plug during this step.
Step 2: Check for Spark
With the spark plug removed but still connected to the spark plug wire, turn over the engine of the lawn mower. Look closely to see if a spark is being generated at the tip of the spark plug. This visual inspection will help determine if the ignition coil is functioning properly.
Step 3: Perform a Spark Tester
If the visual check did not yield conclusive results, consider using a spark tester to further analyze the ignition coil’s performance. A spark tester is a handy tool that can provide a more accurate assessment of the ignition system’s functionality.
Step 4: Measure the Resistance
Another method for testing the ignition coil is to measure its resistance with a multimeter. By checking the resistance levels of the ignition coil, you can determine if it falls within the manufacturer’s specifications. Any deviations from the recommended resistance values may indicate a faulty ignition coil.
Step 5: Inspect for Physical Damage
While testing the ignition coil, be sure to visually inspect it for any signs of physical damage or wear. Cracks, burns, or other visible defects could be indicative of a malfunctioning ignition coil that needs to be replaced.
Step 6: Consult the Manufacturer’s Instructions
If you are unsure about how to proceed with testing the ignition coil on your specific lawn mower model, it is always a good idea to refer to the manufacturer’s instructions and guidelines. Following the recommended procedures can help ensure an accurate assessment of the ignition coil’s condition.
